That's the code guys. I've been working on it now for long, I just can't find a way to get pass the placing or order section. I'd appreciate your help. Thanks

 
If you are looking for the highest price and lowest price in the range from bar #0, you will never get your signal. Look in the range from bar #1 - then the 'close' price will be able to overcome the highest or lowest price.
 
Thanks Sir. But whtat exactly do you mean by that?

Bar #0 cannot be used in the algorithm for finding the highest and lowest prices.

void CChannelBreakout::GetHighestHighAndLowestLow(int &BarsHigh, int &BarsLow)
{
//+--------------------------------------------------------------------+
//|Firstly, declare the arrays to hold the candlesticks highs and lows |
//+--------------------------------------------------------------------+
      double High[];
      ArraySetAsSeries(High,true);
      CopyHigh(_Symbol,PERIOD_CURRENT,0,BarsHigh,High);
      
      double Low[];
      ArraySetAsSeries(Low,true);
      CopyLow(_Symbol,PERIOD_CURRENT,0,BarsLow,Low);
//+-------------------------------------------------------------------------------+
//|Secondly, declare the variables to hold the array numbers which is the highest |
//+-------------------------------------------------------------------------------+
      int HighestHighArrNo  = ArrayMaximum(High,0,BarsHigh);
      int LowestLowArrNo = ArrayMinimum(Low,0,BarsLow);
//+-----------------------------------------------------------------------------------+
//|Thirdly, declare the arrays to hold the value of the highest high and lowest lows  |
//|from the array number                                                              |
//+-----------------------------------------------------------------------------------+
      HighestHighValue = High[HighestHighArrNo];
      LowestLowValue   = Low[LowestLowArrNo];
}

Ok thanks. But problem keeps persisting. Do you think there's any other thing I have to do?

You haven't done anything. Correct the error and show your code.

 
Ok.... I'll do so now
  
void OnTick()
  {
      double high[];
      ArraySetAsSeries(high,true);
      CopyHigh(_Symbol,PERIOD_CURRENT,1,11,high);
      
      double Low[];
      ArraySetAsSeries(Low,true);
      CopyLow(_Symbol,PERIOD_CURRENT,1,11,Low);
      
      int HighestHighArrNo  = ArrayMaximum(high,0,10);
      int LowestLowArrNo = ArrayMinimum(Low,0,10);
      
      double HighestHighValue = high[HighestHighArrNo];
      double LowestLowValue   = Low[LowestLowArrNo];


      double close[];
      ArraySetAsSeries(close,true);
      CopyClose(_Symbol,PERIOD_CURRENT,0,1,close);
      
      if(close[0]>HighestHighValue)
         Print("Buy");
      if(close[0]<LowestLowValue)
         Print("Sell");

Sir I did this, and now the EA just keeps opening positions on it own. And still the problem persisits

The EA is now looking for the maximum (and minimum) price correctly.

While your mistake is that you do not control the number of positions (check the number of positions before checking the signal).

//+------------------------------------------------------------------+
//| Expert tick function                                             |
//+------------------------------------------------------------------+
void OnTick()
  {
   if(PositionsTotal()==0)
     {
      double arr_high[],arr_low[];
      ArraySetAsSeries(arr_high,true);
      ArraySetAsSeries(arr_low,true);
      int start_pos=1,count=11;
      if(CopyHigh(Symbol(),Period(),start_pos,count,arr_high)==count && CopyLow(Symbol(),Period(),start_pos,count,arr_low)==count)
        {
         int high_max_index   = ArrayMaximum(arr_high,0,WHOLE_ARRAY);
         int low_min_index    = ArrayMinimum(arr_low,0,WHOLE_ARRAY);
         double highes        = arr_high[high_max_index];
         double lowest        = arr_low[low_min_index];
         //---
         double arr_close[];
         ArraySetAsSeries(close,true);
         start_pos=0,count=1;
         CopyClose(Symbol(),Period(),start_pos,count,arr_close);
         if(arr_close[0]>high_max_index)
            Print("Buy");
         if(arr_close[0]<low_min_index)
            Print("Sell");
        }
     }
  }
 
Thanks Moderator, but problem keeps persisting even after using your code, they there where some few syntax errors in the spellings, but then the program keeps placing trades as it wants to, not following the signal

If you find two mistakes - you are great :) - then you are a thinking person!

I have provided the simplest code - in order to accurately control the number of positions, you need to control the execution of trade orders.

An example of how to catch a trade transaction:

How to start with MQL5

We catch the transaction

Code: We catch the transaction.mq5

We catch the transaction


This is a blank - an example of how to control a trading signal. This code avoids the situation: opening multiple positions. How it works: after a trade order is generated, we increase the 'SPosition' structure. In OnTick, if 'SPosition' is greater than zero, go to the block for opening positions. In OnTradeTransaction, we monitor the situation when a position appears exactly on our signal.
